The VAM Lerma was an automobile designed and manufactured by Vehiculos Automotores Mexicanos in the early 1980s. The car used common parts from other vehicles by VAM's license partner American Motors (AMC) to cut down manufacturing costs.
The name for the cars was taken from Lerma, a city in the state of Mexico, where VAM engines were manufactured.
The made in Mexico Lerma was a unique hybrid since it used a chassis and some body panels from a sedan similar to the AMC Concord, but the rear of the car featured a hatchback design. Although the Lerma was a single unit body design (monocoque), a British newspaper article erroneously described it as "a bolt-together kit of a car".
There were two body styles available, a 3-door hatchback and a 5-door hatchback (a body style not available for any of AMC's models at that time). Although presented to AMC's management as a potential model for other markets, the Lerma was marketed only in Mexico starting in 1981, and competed in an expanding market segment. The Lerma's most remarkable and striking hatchback design feature also proved to be its biggest drawback, because the shortened rear end resulted in a car with a limited space for storage. Nevertheless the car sold well in Mexico and between 1981- and 1983 was the best selling car in the country
It is believed that the VAM Lerma was the first successful fully Mexican sedan. Vehiculos Automotores Mexicanos is remembered as the first Mexican automotive company that created a car that is regarded by many as totally national. Although the Lerma was conceived in Mexico, it cannot be considered completely Mexican, since many parts and components were designed and manufactured in the United States. However, with the exception of the instrument panel, the elegant interior of the Lerma did not copy of any model and featured uniquely designed and upholstered seats as well as interior door panels.
